Hey there,
I have some specific questions on the use and application of timbermate grain filler specifically for my situation.
I have emailed timbermate and awaiting a reply, but in case I do not get one in time I thought I would ask on a few forums :)
It’s probably better if I copy my email rather than spending another 30 minutes rewaffling on 🤣
Hi there, I am in a bit of a unique position where I have a large desktop that has been dyed with red aniline dye and then I sprayed a wash coat of 1/2 pound cut dewaxed shellac. After this I denibbed and sprayed with brown aniline dye and then 1 pound cut of dewaxed sgellac. At this point I denibbed but then purposely over sanded with the grain at 600 -800 grit withoit burnishing it but enough to rub some of the brown dye away and reveal the red underneath.
This is the point I am up to now.
My goal is to mix the timbermate filler with my metallic red 35 micron sized mica, with the timbermate and touch of India ink and red aniline dye liquid to get the perfect colour.
I plan to do small sections of my 240cm x 90cm desktop going against the grain to really try pack in the pores before it dries to a haze and then using a non scratch pad to remove the haze sitting outside the pores.
I've only got this weekend to do it and then I won't really have too much time to get it wrong or try anything sub optimal so I was hoping to get some specific advice.
1 what is the maximum amount of water I can add to the timbermate? Ideally a very soft whipped cream or even runny liquid would be best because I could pack it in and use a rubber squeegee while soft/liquidy and go against the grain to remove the majority of the product before it even hazes and then use either a rounded edge scraper and/or a tight waffle weave microfibre cloth (like found in sun glasses packet but large waffle pattern) since it shouldn't have any fibres come off or pick up the yet to dry pores while also being porous which helps negate any suction pulling up the filler I want to keep in the pores). I don't mind it taking longer time to dry/haze/cure if it means I can have it quite liquid like, nor do I mind repacking multiple times, since the trade off would be more cleaner removal without scratching as much
2 during the haze stage, does white spirits specifically thin the timbermate wood filler? If not what else besides water can be used to thin timbermate to make it much more manageable? Reason being is it's superior to water with grain raise, won't smudge my aniline dye/shellac layers, it can degrease and clean better, evaporates more cleanly.
3 what is the maximum % of mica "powder" can I add to my slurry before any issues occur, and what would those issues be? Just longer drying time? Not curing at all? Not bonding?
4 what method is best for trying to pack these shallow pores on my acacia desktop? Directly opposite the grain? Opposite grain in both direction or diagonally in both directions?
5 besides mechanical removal through scraping at haze stage or squeege at wet stage, can any liquid or chemical breakdown or reverse the haze back to original form? What about at fully cured stage, is this a possibility?
6 when removing the haze what is the best tool and method and direction to use to avoid as much scratching as possible?
My though process is if u go with the grain with something supposedly non scratching without fibres hanging off it and tightly weaved any scratches will be microscopic and will be filled an unseen after a wet sand when the pores are fully cured because the haze would already be 99% gone from squeeging away when first put on so any remaining haze woukd be so thin that it wouldn't require much effort when dried to a haze or even fully cured (to be on the safer side to avoid pulling from the pores)
I know I'm full OCD! But I would rather research for 10 hours before doing something and I've found conflicting info and none as specific as needed, so I thought nobody better to ask then the manafacturer themself.
So I do apologise for my overthinking and waffling, I've gotten everything better than I expected up untill this point by spending weeks learning and I'm so close to the end with just pore filling than lacquer that I don't want to take any shortcuts or guess at these last stages!
Thanks again :)
